US 11,388,675 B2 · Dynamic data rate selection

Abstract

Dynamic data rate selection in wireless networks is described. The includes sending, by a wireless controller to a base station, an access point power-data rate table. The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.

A method for dynamic data rate update, the method comprising:

sending, by a wireless controller to a base station, an access point power-data rate table;
updating, by the base station, a base station power-data rate table with the access point power-data rate table based on checking defined thresholds;
confirming, by the base station, the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table;
reverting, by the base station, to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct;
sending, by the base station to the wireless controller, one of the updated base station power-data rate table or the previous base station power-data rate table;
updating, by the wireless controller, the access point power-data rate table with a received base station power-data rate table;
and
sending, by the wireless controller, updated access point power-data rate table to an access point.

5 more elements

A system comprising:

a plurality of wireless access points, each wireless access point having a signal power and data rate table;
at least one Citizens Broadband Radio Service (CBRS) device (CBSD) having a signal power and code rate table;
and
a wireless controller configured to send a signal power and data rate table to the at least one CBSD based on a defined event,
wherein the at least one CBSD is configured to:
determine whether updating thresholds are met by comparing aspects of the signal power and data rate table with the signal power and data rate table;
and
confirm viability of updated signal power and code rate table when updating thresholds are met;
and
send the updated signal power and code rate table when confirmed;
and
wherein the wireless controller is configured to:
update each signal power and data rate table based on the updated signal power and code rate table when the updated signal power and code rate table is received;
and
send a respective updated signal power and data rate table to each wireless access point of the plurality of wireless access points.
